HARRY PERRINS, OI SMETI-IWICK, ENGLAND,

,WHEEL FOR MOTOR AND OTHER ROAD VEHICLES.

To all whom it may concern:

Be it known that I, HARRY PERRINS, a subject of His Majesty the King of Great Britain and Ireland, residing at Oakdene, Bearwood Road, Smethwick, Staflordshire, England, engineer, have invented new and useful Improvements in lVheels for Motor and other Road Vehicles, of which the following is a specification.

This invention has reference to that type of wheel for motor vehicles and for other road vehicles which is arranged to be fitted with a pneumatic tire and is formed of two stamped sheet metal disks bulged outwardly toward the hub and also at their periphery where they are fixed together at the proper distance apart by a metal ring fitting between them and secured by cross bolts said disks being gripped at the hub between a central distance block and two side flanges.

My invention consists of the herein described improved construction, combination and arrangement of the parts of a Wheel of this type so as to facilitate the removal of a damaged tire and the replacing of the same ;by a new tire,

wheel are arranged in accordance with this invention, can be done very expeditiously. Moreover my said invention adds considerably to the rigidity of the wheel.

I will describe my invention by referring to the accompanying drawings on which- Figure 1 is a cross sectional elevation of a wheel constructed in accordance with this invention for motor andother road vehicles; Fig. 2 is a half front elevation of the same; Fig. 3 is a sectional elevation of one of the disks and the hub part of the wheel; Fig. 4 is a sectional elevation of the other disk of the Wheel; Fig. 5 is a cross sectional elevation of the trough section wheel rim which I usein combination with the disks to form the wheel; Fig. 6 shows one ofthe cross bolts of the wheel'in'elevation; Fig. 7 is the nut of the screw; Fig. 8 is a sectional elevation of the distance block part of the hub; Fig. 9 is a front elevation of the said distance block; and Fig. 10 is a sectional elevation of the end disk which screws on to the hub.

In carrying out this invention the two disks 1, 2, forming the sides of the wheel are as heretofore at their peripheries turned inwardly and bulged outwardly at 3, 4, slightly within the peripheries, thereby forming an annular channel or groove 3 on the Specification of Letters Patent.

Application filed January 27, 1909.

which when the parts of the Patented Nov. 15, 1910.

erial No. 474,505.

inner face of the disk 1 anda similar annular channel or groove 4 on the inner face of the disk 2 near the peripheries of these disks. The metal ring 5 which I use in combination with these two disks 1, 2, is av trough section wheel rim (shown separately in Fig. 5) made with inturned edges 6 adapted to receive the outer cover and inner airztube of the pneumatic tire and the bulged sides 7 8, of this rim are made of the proper size to fit in and between the annular grooves 3, 4, which are stamped or otherwise formed around the peripheries of the twodisks 1, 2, as aforesaid.

In order to render the wheel rigid, and particularly when the wheel is a driving wheel, the portions 9, 10 of the disks 1, 2, respectively which are grippedbetween the outside flanges 11, 12, of the hub and the central distance block 13, are stamped orv otherwise formed with radial ,or other projections 14, preferably four in number, .or there may be fewer or more than four. pro+ jections, on the sides of the disks next to. the central distance block 13 the faces of which are correspondingly grooved at 15for these projections 14 to fit into so that when the disks 1, 2, and the central distance piece 13 are mounted on the central-boss or axle box 16 of the wheel and are clamped together by the flange 12 bein 'screwed on to the screwed end of the hu '16, the side flanges 1, 2, and the distance block 13 will be gripped firmly together and by the projections 14 of the disks fitting in the recesses 15 of the distance piece 13 it will be-impossible for one disk to be turned in the smallest degree without turning the other disk also. In order to prevent the distance piece 13 and the disks 1, 2, from turning on the hub 16 the latter is on its exterior surface at 28 made hexagonal or of other shape than round, or is made round and fitted with one or more keys, and the interior of the dis-- tance piece 13 is at 29 made of corresponding shape and size so that these two'parts fit together and the one is prevented from turning on the other. Any convenient number of bolts or screws such for instance as the bolts 31 are passed through holes 17 I 18, in the disks and secured by nuts such as 19 and arranged as near as convenient to the rim 5 so as to clamp-the grooved parts 3, 4, of the disks 1', 2, tightly against the sides'7, 8, of the ring or rim 5 which is thereby firmly and securely gripped in the grooves 3, 4; and any creeping is effectuallypre-- A ,up the disk 12 and the'outsidenut 26. Thus.

The bolts 31 by .which the'fianges 1,. 2', "are secured together as aforesaid are by prefer-v vented.

ence made as follows':The bolt 31 has a square neck underneath its head to fit in f g to secure by Letters Patent 1s a correspondingly-- shaped hole 17 in the disk 1 and there the bolt is bush 32 (Fig. 1) which-is tapped at one end and is screwed on to the art 21 of the bolt 31, so as to firmly ip t e disk 1. between the head 22 of thegblt and the. end of the I bush 32. This bush'32 is made of just the proper length to suit the distance between the disks at the holes 17, 18. 'The'other disk 2 fits against the outer end of the bush 32 and is there secured by the'nut 19 being screwed on to the screwed'end 23 of the bolt 31 so. as to clam the disk 12' between the washer 24 on the olt 31 and the outer end of the bush 32. This bush must be made of the, proper length so that when the nut is screwed up as aforesaid the grooved ring 5 will be properly gripped between the sides 3, 4, 'of the disks 1, 2. The nut 19'islby preference made with acap 25 to rotect-the end of the boltfrom corrosion. crewed. on the hub at 16 outside the disk 12 there is the usual ca nut 26 which is screwed on to the end of t e hub oraxle box 16 to cover the nut 27 on the end of thesaxle 30. It will be i seen that by first removing the nuts 19 from the screws 31, the disk 2 is then free to' be removed and the rim 5, with the pneumatic tire inflated or deflated thereon, can be removed and replaced with another similar rim 5 and pneumatic tire if required, and this can quickly be refixed place -'by re placing the disk 2' and securlng it by the Secured by the nuts 19 on thebol'ts 31 and then screwing the rim 5 with a punctured tire thereoncan in the space of a few minutes be removed and replaced by another rimfand tire.

What I claim as my invention, and desire the adjacent face of each of which has a' circumferential groove at or near its periphery, a central hub or axle box on which the disks are mounted furnished with one fixed and one removable flange outside said disks and a detachable distance block mounted on saidhub or axle box so as not to turn-thereon between said disks which latter are stamped with projections engaging in reseparating.

cesses in the distance block to prevent the f disks turningvon the hub or axle box or turnin independently of one another, substantia 1y asIset forth. v i

In testimony whereof I have signed my name to this specification two subscribing witnesses.
